TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, RICHARD F. BRIGGS, of Amesbury, in the county ofEssex, and State of Massachusetts, have invented an improved FoldingSeat for Carriage Bodies; and I do hereby declare that the same is fullydescribed and represented in the following specification andaccompanying drawings, of wh'ich Figure 1 is a side view, with the seatin its upright position.

Figure 2 is a side view with the scat folded against the dasher. V

Figure 3 is a side view, with the scat folded back in the centre of vthebody.

In the drawings I have represented a carriage body such as is ordinarilyused on oneseated vehicles, with my improvements applied to it.

The nature of my invention or improvement consists in so supporting theseat that it may be folded against the dasher or back into the centre ofthe body, or maintain an upright position, by means of two stationarysupports extending upright from the sill of the body, one to each end ofthe back part of the seat, and by two supports attached by movablejoints to the front of the seat at suflicient distance apart so they maybe enclosed or pass by the above-mentioned upright supports, said frontsupports being attached to the sill of the body by movable joints at apoint to the rear of a. vertical line passing through the centre of theseat when in its upright position, thus enabling the seat to pass overthe upright stationary supports at the back thereof, when it is foldedback into the centre of the body. The seat is secured in its uprightposition by means of a frictionplate or laceextending across and undereach end of the seat, said plate having a slot out across at the rearcndothcreof, which is received by a corresponding slot in-thc top ofthcupright stationary supports above mentioned The construction,arrangement, and operation of my invention 1 will proceed to explain,reference being had to theaccompanying drawings, in which similarletters represent similar parts.

Letter :1, the seat. Letter 71, one of the front supports of seat a.Letter 0, one of the rear stationary supports of seat a. Letter (1, theslotted friction-plate secured across the'end-of seat a. Letter 0, thepinion by which support I) is attached to seat a. Letter f, the pinionby which support b is attached to the sill of the body. Letter 5 theslot in friction-plate (1. Letter 71, the slot in upright stationarysupport a, which receives the slot in friction-plate d.

In the construction of my folding seat I attach front support b, bymeans of pinion e, to the front of seat a, at a point distant from theend thereof, so .s to allow support I; to clear or pass by stationaryupright c. I

- also attach'thc lower end of support b to the sill of the body, bymeans of pinion f, at a point slightly to the rear of a vertical linepassing through the centre of seat a, when in its upright position.Pinion e is firmly secured to seat a, and .pinion f to the sill of thebody, and they are the points on which support 6 turns when the seat isfolded to the front or fear. I secure stationary upright support a tothe sill of the body, at a point distant from pinionf slightly less thanone-half of the width of seat a, and further from the centre of the bodythan pinion f, so that when the seat is folded back, support Z; willconic inside of support a. I cut a slot in the. top of' support-c, toreceive a slot in friction-plate d, to be hereinafter described. Isecure friction-plate d to the end of seat a, said plate being firmlyriveted thereto, and containing a slot at the rear end thereofcorresponding to the slot in support 0. The slot in friction-plate d,represented in the drawing by letter g, and the slot in upright support0, represented by letter l1, when pressed together, give firmness andstability to the seat in its upright position. I

In this description of the construction and arrangement of myfoldingseat I have confined myself to the mechanism required to operate one endonly; the other being the exact duplicate, I have avoided itsdescription as much as possible.

The operation is as follows: The seat being in its upright position, itcan be folded against the dasher by slightly elevating thelback part of,theseat sufiicient to disengage the slots g and h, and by its own weightit will fold up against the dasher. The seat can he put in its erectposition by raising it until the friction-plates strike the statioiiaryuprights, when the slots will readily meet, and secure the seat firmly.To fold the seat I back into the centre of the body, disengage the slotsby raising the back of the seat, and throw it back, which will permit asecond or back seat to be drawn forward and used as a one-seatedcarriage.

l: have not dcscribed the second or back seat, as I lay no claim tothat; but what I claim, and desire to secure by Letters Patent, is- I vThe combination andhrrangement of the support I), slotted friction-plated, and slotted upright support 0, substantially as described for thepurpose herein set forth.
